As someone who is a minimalist and wanted a one-bag kind of setup, this truly is that bag. The only downsides for me are the zipper pockets inside the bag are not very functional and the laptop compartment runs a bit deep for my liking. All in all, though, I am beyond happy with this purchase!
Was about to go for the 45L, but thankfully I spotted this option in time. Most of the time, the backpack is perfectly sized for my camera kit. Love having the option to extend it, when I might need a little bit of extra room.
This is what I manage to fit in the backpack:
A7RIII + 20mm 1.8 G A1 + 35mm 1,2 Art A1 + 70-200mm 2.8 GM Mavic 2 Pro + Smart controller 14" laptop
Having used backpacks for over 30 years in my nature photography endeavors, I prefer an ergonomic yet robust backpack to carry my Leica SL2S kit and drone. I opted for the 30L, along with the optional belt strap. The unit was clearly designed with a photographers view for full functionality and comfort in a visually - appealing design.
